The 2x PoD is probably for other classes but “may” come into play vs some DH decks, but again, probably not why it’s in here.

What DH decks are you referring to saying that this deck is “NOT good”? This build has plenty of answers for DH. At worst this deck is even with most DH decks and at best this one is favored. Holy Nova, pyro, and Breath for board wipe and soul mirror. Renew, penance, apotheosis, pyro+apotheosis, and artificer + penance for life gain Death and time rip for bigger removal. Galakrond and Kronx both are possible removal and help you live.

I’m not saying this deck stomps X or is best deck ever, I am saying though, it is certainly better than “NOT good”. So I’m curious to know why you say that. I’d be interested to see your reason.
